Perry used the formula V (t) = 24,450(1-0.13) to find the value of his car t years after he purchased it.

What does 0.13 represent?

A the price of the new car

B the time of year the car was purchased

the value of the car after t years

a 13% decrease in value each year

D) a 13% decrease in value each year

Step-by-step explanation:

Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.

What does 0.13 represent?

The expression given above represents and expression of exponential decrease.

This is represented by the formula

y = a(1 - r)^t

Where

y = Value after time t

a = Initial value

r = Rate of decrease

t = Time

Comparing both expressions

y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t

We can see that:

r = 0.13

This is the rate of decrease.

Converting to Percentage = 0.13 × 100

= 13%

Option D is the correct option.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
